More space news and info at: http://www.coconutsciencelab.com - using data from NASA's Kepler Space Telescope, scientists have discovered a planetary system of five small planets dating back to when the Milky Way galaxy was a youthful two billion years old. The tightly packed system, named Kepler-444, formed 11.2 billion years ago, when the universe was less than 20 percent its current age. This makes Kepler-444 the oldest known star system with terrestrial-sized planets, two and a half times older than the Earth. The star system is home to five planets - the smallest comparable to the size of Mercury and the largest to Venus. All five planets orbit the sun-like star in less than ten days, which makes their orbits much closer than Mercury's sweltering 88-day orbit around our sun. Please rate and comment, thanks!
